Abstract

A FLUID RECIRCULATION SYSTEM (30) INCLUDES AN ARRANGEMENT OF A FLOW CONTROL VALVE (50) LOCATED TO RECEIVE A FLOW OF FLUID FROM AN INLET. THE SYSTEM (30) FURTHER COMPRISES AN ECONOMIZER INLET MIXING DEVICE (54) LOCATED TO RECEIVE THE FLOW OF HOTTER FLUID FROM THE ARRANGEMENT OF THE FLOW CONTROL VALVE (50) AND FROM A COOLER FEEDWATER STREAM. AN ECONOMIZER INLET MIXING DEVICE (54) LOCATED UPSTREAM OF AN ECONOMIZER (22) IN A SUPERCRITICAL PRESSURE BOILER (10) INCLUDES A SPARGER ASSEMBLY THROUGH WHICH A FLOW OF FLUID FROM THE WATERWALL (14) OUTLET IS RECEIVED, AN INLET THROUGH WHICH A FLOW OF FLUID (37) FROM A FEED STREAM IS RECEIVED, AND A WAVE BREAKER ASSEMBLY (84) THROUGH WHICH AN OUTLET STREAM FROM THE ECONOMIZER INLET MIXING DEVICE (54) IS DIRECTED. A METHOD OF INCREASING AND CONTROLLING THE TEMPERATURE OF A FLUE GAS EXITING AN ECONOMIZER (22) IN A SUPERCRITICAL PRESSURE BOILER (10) INCLUDES RECEIVING AT LEAST A FLOW OF FLUID FROM A FLUID STREAM (37) FROM A FURNACE (12) WATERWALL (14) OUTLET, COMBINING AT LEAST A PORTION OF THE RECEIVED FLOW OF FLUID (37) WITH A FEEDWATER STREAM, AND DIRECTING THE COMBINED RECEIVED FLOW OF FLUID (37) AND FEEDWATER STREAM TO AN ECONOMIZER (22) INLET TO DECREASE THE ECONOMIZER (22) HEAT ABSORPTION.
